Well I have noticed an improvement in battery life since I disabled fast dormancy. I probably need to test it more though. In any case, the constant switching between "H" and "3G" was really annoying; glad that's over with!

A phone switching between 3G and H is perfectly normal. A phone establishes a connection to the rel 99 3G channel and only switches to HSDPA / HSPA+ on demand through a state change as required. Once the HSDPA / HSPA+ resources are no longer required it will switch back to the rel 99 3G mode again and (typically) enter a sleep mode.

My HTC Desire has never entered shown 3G, from the original Telstra stock rom to the custom sense roms that i used, to the gingerbread AOSP roms, cyanogenmod, and now Cyanogenmod9 based on ice cream sandwich. When i have mobile data enabled, its a solid H the whole time.

Yes, but in my case it would constantly switch multiple times within a span of a few seconds.. that can't really be good for the battery, right?
